Monitoring Predefined Objects

RTMT provides a set of default monitoring objects that assist you in monitoring the health of the system. Default objects include performance counters or critical event status for the system and other supported services.

Monitoring Server Status

The Servers category monitors CPU and memory usage, processes, disk space usage, and critical services for the different applications on the server.

The CPU and Memory monitor provide information about the CPU usage and Virtual memory usage on each server. For each CPU on a server, the information includes the percentage of time that each processor spends executing processes in different modes and operations (User, Nice, System, Idle, IRQ, SoftIRQ, and IOWait). The percentage of CPU equals the total time that is spent executing in all the different modes and operations excluding the Idle time. For memory, the information includes the Total, Used, Free, Shared, Buffers, Cached, Total Swap, Used Swap, and Free Swap memory in Kbytes, and the percentage of Virtual Memory in Use.

The disk usage monitoring category charts the percentage of disk usage for the common and swap partitions. It also displays the percentage of disk usage for each partition (Active, Boot, Common, Inactive, Swap, SharedMemory) in each host.

The Critical Services monitoring category provides the name of the critical service, the status (whether the service is up, down, activated, stopped by the administrator, starting, stopping, or in an unknown state), and the elapsed time during which the services are up and running on the system.

The service currently exists in start mode, as indicated in the Critical Services pane and in Control Center in Cisco Unified CallManager Serviceability

up

The service currently runs, as indicated in the Critical Services pane and in Control Center in Cisco Unified CallManager Serviceability.

stopping

The service currently remains stopped, as indicated in the Critical Services pane and in Control Center in Cisco Unified CallManager Serviceability.

down

The service stopped running unexpectedly; that is, you did not perform a task that stopped the service. The Critical Services pane indicates that the service is down.

The CriticalServiceDown alert gets generated when the service status equals down.

stopped by Admin

You performed a task that intentionally stopped the service; for example, the service stopped because you backed up or restored Cisco Unified CallManager, performed an upgrade, stopped the service in Cisco Unified CallManager Serviceability or the Command Line Interface (CLI), and so on.

The Critical Services pane indicates the status.

not activated

The service does not exist in a currently activated status, as indicated in the Critical Services pane and in Service Activation in Cisco Unified CallManager Serviceability.

unknown state

The system cannot determine the state of the service, as indicated in the Critical Services pane.

Tip To zoom in on the monitor of a predefined object, click and drag the left mouse button over the area of the chart in which you are interested. Release the left mouse button when you have the selected area. RTMT updates the monitored view. To zoom out and reset the monitor to the initial default view, press the "R" key.

Description

System Summary

Displays information on Virtual Memory usage, CPU usage, Common Partition Usage, and the alert history log.

To display information on predefined system objects, choose System > System Summary.

Server

•CPU and Memory—Displays information on CPU usage and Virtual memory usage for the server.

•Process—Displays information on the processes that are running on the server.

To display information on processes running on the system, choose System > Server > Process. To monitor process usage for specific server, choose the server from the Host drop-down list box.

•Disk Usage—Displays information on disk usage on the server.

To display information on disk usage on the system, choose System > Server > Disk Usage. To monitor disk usage for specific server, choose the server from the host drop-down list box.

•Critical Services—Displays the name of the critical service, the status (whether the service is up, down, activated, stopped by the administrator, starting, stopping, or in an unknown state), and the elapsed time during which the services have existed in a particular state for a particular Cisco Unified Communications node.

To display information on critical services, choose System > Server > Critical Services. To display system critical services, click on the system tab.

–To monitor critical services for specific server, choose the server from the host drop-down list box and click the critical services tab in which you are interested.

If the critical service status indicates that the administrator stopped the service, the administrator performed a task that intentionally stopped the service; for example, the service stopped because the administrator backed up or restored Cisco Unified Communications Manager, performed an upgrade, stopped the service in Cisco Unified CallManager Serviceability or the Command Line Interface (CLI), and so on.

If the critical service status displays as unknown state, the system cannot determine the state of the service.
